Pneumatic conveyor

l Pneumatic conveyor overview  

l 氣體輸送的概念         

l  功用：運用風機在封閉的管路內形成氣流來輸送散料物料。

l  工作原理：將物料處于具有一定速度的空氣中，通過管道輸送到卸料點，然后將物料分離出來，從而達到輸送物料的目的。Function:use the fan in a closed form air flow in the pipeline to transport bulk materials.

Working principle:the material in the air at a certain speed, through pipes to the unloading point, and then to isolate the material, so as to achieve the purpose of conveying material.

l The classification of the pneumatic conveyor

l氣力輸送的分類

l  氣力輸送機分為吸送式氣力輸送機，壓送式氣力輸送機和混合式氣力輸送機

l  Pneumatic conveyor are divided intopneumatic conveyor，inhale conveyor and the hybrid pneumatic conveyor

1.Pneumatic conveyor with delivery壓送式氣力輸送機

The working principle of工作原理
由于高壓氣體的作用，物料從發送罐進入輸送管，壓縮氣體經電磁閥的開閉形成脈沖氣流，（氣刀）當氣刀壓力大于發送罐壓力時，氣流將物料切割成料，依靠料栓前后的靜壓差作推動力，將物料推向前進，到達分離裝置實施料氣離后，物料落入料倉，氣體排入大氣實現輸送。Due to the effect of high pressure gas, material from sent tanks into the duct, compressed gas by the solenoid valve opening and closing of the pulse jet formation, (air knife) when air blade pressure is greater than send tank pressure, airflow to the material cutting ChengLiao, rely on the material before and after the static pressure difference as a driving force of bolt, the material forward, reach the separation device to implement material gas, after the material into the bin, gas atmosphere  implementation.      

技術參數 

The characteristics of特點

1、輸送速度較小，對管路的磨損少。

2、控制必須是自動化，對各種電氣元件的要求高。

3、輸送路程長，可以達1000m以上。

4、可以在輸送管內外設補氣管，并用多種方式補氣、排堵但電控復雜。

5、發送罐(也稱倉泵)是壓力容器，為強制性簽定設備。

6、維護要求很高對維護技術人員的素質要求亦很高。

1, delivery speed, smaller pipe less wear and tear.
2, control must be automated, high to the requirement of all kinds of electrical components.
3, long transmission distance, can reach more than 1000 m.
4, can fill in conveying tube peripherals trachea, and use a variety of ways to fill gas,but electric control complex.  
5, send tank (also known as warehouse pump) is a pressure vessel, for mandatory sign equipment.
6, a high maintenance requirements in maintaining the quality requirements of technical personnel is also very high.

2.Carrying the pneumatic conveyor吸送式氣力輸送機

The working principle of工作原理

吸送氣力輸送一般用羅茨真空泵作動力源，將管路及罐式倉抽成一定的真空狀態促成進風口在大氣壓的作用下形成物料粉粒料與氣體的兩相流，經輸送管道輸入旋風分離器。兩相流在旋風分離器內由于離心力及重力作用下，使大部分物料與氣體分離。少量的物料與氣體進入除塵器。通過濾袋作用使粉料與氣體分離。氣體排入大氣。

Carrying the pneumatic conveying roots vacuum pump as power source, is commonly used in the pipeline and tank storage into a vacuum state  to air inlet formed under the action of atmospheric pressure, material powder material and the two phase flow of gas, the pipeline type cyclone separator.Two phase flow in the cyclone separator due to centrifugal force and gravity, so most of the material and gas separation.A small amount of material and gas into the dust.Through the filter bag make powder and gas separation.Gas discharged into the atmosphere.

 The characteristics of優勢
1，環保、可靠性**，管路內的粉塵不會泄漏于環境。

2、設備的制造、維護要求低，工人的可操作性強。

3、使用的壓力(真空度)小，安全性高。

4、氣體(一般為氣體)取自大氣，氣體的溫度即為當時當地的氣溫，對熱敏性物料尤為適宜。

5、輸送為連續式、亦可間斷，管道內無積存。

6、易實現多點進料，多點卸料的輸送工程目標。

7、氣體動力源一般為離心風機、羅茨風機(泵)，使用壽命長
